That was great to read. Dang it all! So I've misinterpreted the
assumed_gamma and display_gamma meanings all this time!? I was going by
a assumed_gamma 2.2 being needed to equal the display_gamma, not a 1.0
multiplied by 2.2 kind of way (is that even right?). I know my monitor
gamma correction goes from light to dark based upon 1.0 is normal
setting, less than one is darker, more than one is lighter; so this
would be opposite that.
If I ever used assumed_gamma in a scene it has been 2.2 and then up or
down from there. I'll check this out and see how it all looks compared.
What's odd is that if no global_settings gamma is set at all then
shouldn't the image appear as if assumed_gamma were 1.0? I've never seen
a obvious lightened-up image if so.
Thanks for the good reference page.
